The Block's Ronnie Caceres reveals his top five budget-friendly plants

"You guys may not know this about my husband, the Ron Dog," says The Block's Georgia Caceres, "but he has a genuine plant-hoarding obsession."

In the video above, Georgia stands in her Perth backyard, ready to show us how "out of control" his green habits have become.

"He will pick up plants from wherever he can find them, and collect them," she says. Georgia pans across their outdoor space to reveal a haphazard arrangement of agave plants, an impressive cactus, palms and more.

Their son Leo displays a similar gusto for the green stuff, exclaiming excitedly, "And this is mine!" while picking up a strawberry plant.

Of all things someone can be obsessed with, this seems to be a pretty good choice. 9Homes shares a similar love of plant life, so we reached out to Ronnie to ask him about his obsession and current cheap and cheerful favourites.

9Homes: Why do you love plants so much?

Ronnie:This is going to sound really weird, but my little garden makes me really calm and happy. After a crazy day on the tools, I take my shoes off, grab a beer, water my plants and wind down. I also love propagating plants from cuttings and creating really interesting pot plants using different colours and textures.

H: What are your top five favourite plants?

R: My current obsession is all about the succulents! There are so many different varieties with lots of different textures colours and the best part of it all is that they are so hardy and easy to look after, so it’s no surprise that my top five fave plants are all from the succulent family.

Agave Sttenuata -Love the vibrant colour of the agave and it’s almost impossible to kill these guys making them the ideal plant for time-poor gardeners. I’ve picked up most of my Agaves from mate’s houses, jobs I’ve been working on, or from the side of the road during green waste disposal.

I simply chop off at the base, then plonk them in a bucket of water. Once they’ve rooted, I then plant them in soil. Too easy.

String Of Pearls (Senecio rowleyanus) -Again, these have a lovely vibrant colour. They look awesome sprawling over the edges of containers or hanging baskets. I’ll usually pant three small plants into one medium sized pot as to create more of an immediate impact.

Mother In Law Tongues (Sansevieria) - A really hardy plant, they look awesome mass-planted in pots. Great architectural plant, with their pointy and patterned leaves.

Blue Chalk Sticks (Senecio serpens) - A great ground cover, blue chalk sticks look amazing mass-planted or confined to pots. Does grow quickly so if it’s in a pot, you’ll need to prune it back often. Don’t thouw away the off cuts though, simply stick the cutting in well-draining soil and it will begin to root within the week!

H: What's your pick for a budget-friendly plant that makes a big impact?

R: Succulents! Mix them up, play with different colours and textures for a big impact.

If your budget’s tight, head on over to your mate’s house and raid their garden. Succulents area really easy to propagate from cuttings; some you can simply plonk straight into soil. Others may need to root in water first. Either way, succulents are a cheap and affordable way to create style and impact in your garden.

While Ronnie has a total green thumb, Georgia loves to upcycle. Watch below to see how she transforms a Gumtree find into an amazing piece for the kids' bedroom.
